911SC Power Window Conversion Question
 

I am in the process of converting my 78 911SC from manual to power windows. I contacted Oklahoma Foreign Porsche salvage and they told me that I would require new windows because the channel at the bottom of the glass is different for manual vs power window applications. I took off the manual window regulator and am looking at the existing window and see no difference between what they sent me vs what I have. Anyone know if there is a difference?

I updated my '77 orig PW from 2 arm to 2 arm w/additional arm support. Make sure you have updated regulator. So the part # for 74-79 man is 911 542 929 03[manual left]. 74-86 is 911 542 935 28 [elec. left] I cleaned window sw. and inst. new moldings. I also did elec. door locks, but that is another story. http://www.pelicanparts.com/support/smileys/fles.gif
